Can't access shared mailbox through API even after granting permissions
Hi, As the title said, I am unable to access a shared mailbox using Graph API 1.0 even after granting the right permissions. I want to know what I'm missing here. The user can see its own emails...
The "Access to OData is disabled." message signals that an application access policy is configured, restricting API access to the mailbox. Work with the Exchange admin to lift the restrictions or whitelist your app. More details here: https://practical365.com/application-access-policies-in-exchange-online/
